This can happen if object creation was transactionally undone, and database
was packed.
Update test.

Also, use getOID to generate tightly consecutive TIDs.

This requires explicitly collecting garbage if we get disconnected from
primary master.

Also, improve test (try to break code in tests, don't test unneeded
properties).

A storage might notify the master after the cluster as fall down to the
verification state.

This is used by zodbshootout, for example, to only flush storage's cache.

This should increase process responsiveness when a single _poll call
fetched many packets: as long as packet queue is not empty, no epoll.poll
call was made. This means that outgoing packets were kept in our buffer
until packet queue becomes empty.

Some requests can be safely ignored when received over a closed connection.
This was previously done explicitly in handlers, but it turns out it would
cause a lot of code duplication. Instead, define the policy on a packet
type basis, and apply it to all packets upon reception, before passing it
to handler.
Also, protect request handlers when they respond, as connection might be
closed.

git-svn-id: https://svn.erp5.org/repos/neo/trunk@2419 71dcc9de-d417-0410-9af5-da40c76e7ee4

Those responses are implemented using Error packets.

This change has an important effect on "abort" call in client handler: once
primary master node locked a transaction, a client must not be allowed to
abort it (it already asked to commit).
Also, remove parameter value in abortFor (it is the new default behaviour).
Also, document abort a bit more.

This should improve replication & pack performance.

- set master_conn to None to clarify disconnection
- purge node pool after closing all connections
- allow restarting polling thread after its shutdown
Also, only start polling thread when needed (side-effect of last point).

Otherwise, we would check the same chunk multiple times, if last range
check was successful: at this point, we wouldn't know criterion to find
the first row after replicated chunk.

git-svn-id: https://svn.erp5.org/repos/neo/trunk@2411 71dcc9de-d417-0410-9af5-da40c76e7ee4

This caused incorrect object deletions during replication, when a chunk
lacks rows.

deleteTransaction is used by replication to remove a single transaction but
not its content.

git-svn-id: https://svn.erp5.org/repos/neo/trunk@2407 71dcc9de-d417-0410-9af5-da40c76e7ee4

Otherwise, it might not be called (it connector is not present at
transaction manager's "begin" call time).

If current chunk size is lesser than maximum, it means latest check for the
whole chunk found a problem. If current smaller check succeeded, move to
the other half and divide size by two.
Also, factorise replication "check...Range" handlers.

git-svn-id: https://svn.erp5.org/repos/neo/trunk@2405 71dcc9de-d417-0410-9af5-da40c76e7ee4

This way, it is clear that test doesn't expect replication to end after
current chunk.
